| Abstract: | The local geoid or gravity anomaly as an example is refined by the fusion of the simulated geoid height and gravity anomaly data,and the effects of observation noise level and non-stationary noise to the data fusion results are analyzed.Simulation tests show that the satisfactory results can be obtained by the fusion of different observation noise level data or non-stationary noise data with double-input single-output method. |

| Keywords: | frequency domain input-output system theory data fusion observation noise geoid gravity anomaly |
